Recently shipped Ultrafast mode for GPT-5.6 Sol, Daybreak Blue and Red security tiers, ChatGPT Ads in Europe, and ChatGPT for Teens.

Ultrafast mode brings GPT-5.6 Sol up to 14× faster in the API. Previewing now for select customers, it generates up to 750 output tokens per second, powered by Cerebras. Separately, Fast mode replaced Priority Processing and now handles long-context requests above 272K tokens at up to 2.5× speed.

Daybreak split into two access tiers for approved defenders. Daybreak Blue offers general-purpose models like GPT-5.6 Sol for defensive work; Daybreak Red adds purpose-trained GPT-5.6 Cyber for authorized exploit validation and red teaming. Both are now available through Amazon Bedrock alongside existing AWS availability.

ChatGPT Ads expanded to 31 European markets, including Germany, France, Spain, and Italy, six months after the U.S. test. Ads reach Free users; self-service Ads Manager access follows later this summer.

ChatGPT for Teens launched with automatic placement for users estimated under 18 or aged 13–17, adding parental controls and healthy-use features.

Codex gained multi-repo review, Linux, and third-party imports. GPT-5.4 and GPT-5.4 mini retire from Codex on August 31 with Terra and Luna recommended. API platform additions: GPT Transcribe and GPT Live Transcribe, the OpenAI Terraform provider, a Prompt Caching dashboard, transparent backgrounds in Images API, and API key filtering in Usage and Costs dashboards. Sora video APIs are deprecated.

SDK bumps: all SDKs added Bedrock Runtime support; Python v3.0.0 now defaults to HTTPX2 with breaking migration, and Node v7.0.0 requires Node.js 22.
